A Magnetic Window Antenna Based on Artificial Electromagnetic Structure
2024 International Applied Computational Electromagnetics Society Symposium (ACES)(2024)
Abstract
The problem of the communication blackout when aircraft passing through the atmosphere is still worth further study. Based on the artificial electromagnetic structure which can excite the near-field magnetic field, a novel righthand circularly polarized magnetic window antenna is proposed. In the case of 0.5 T magnetic field, the attenuation is reduced to 14.0 dB through the plasma with a density magnitude of 10
11
cm
−3
. The results show that this approach can significantly improve the communication effectiveness when encountering the blackout caused by the plasma.
